We have a game already available on itunes app store and on Facebook.
We need to change the some graphics (as the current ones look to old) for both iPhone version and the facebook version of the game, it was done in Corona I guess.
You must know Corona or may be Unity3D? As its a 3D Game. Sorry I am not a technical person.
Also need a couple of more new features to the game and a action change require in the game play of the Facebook version of the game (not iPhone, as the iPhone version has fine gameplay)
Should not take more than 5 hours for an experienced developer.
If you need a 5 out 5 ratings :)
